:  |  JSON question -- can any SE regulars help??
Ok, here's the scenario. I have a web app that I'm using AJAX and a web service in.
The AJAX is used to create the ModalPopup.
So I have a JavaScript called ModalPopupFunctions.js that contains a function like this:
function PopulateDropDowns(json)
{
var p, t, s, si;
var ddl = document.getElementById('myDDL');
var opt = document.createElement('OPTION');
eval("p = " + json);
// Priorities Drop-Down List.
removeOptions(ddl,p.DataList.length); // Remove any options that may be present.
// Use the addOption function to populate the correct DropDownList.
for(var i = 0; i < p.DataList.length; i++)
{
addOption(ddl, p.DataList[i].Desc, p.DataList[i].ID);
}
}
function addOption(selectbox,text,value)
{
var opt = document.createElement("OPTION");
selectbox.options.add(new Option(text));
opt.text = text;
opt.value = value;
selectbox.options.add(opt);
}
// Removing options from the appropriate drop down list.
function removeOptions(selectbox, numberOfItems)
{
for(var i = numberOfItems - 1; i >= 0; i--)
{
selectbox.remove(i);
}
}
Now, I can use this to populate a DropDownList (select), but when I view source, it's empty, so I can't get the selected value to pass back to the server. In other words, the DropDownList gets populated, but in some weird way, where if I do a view source all I see is the select open and close markup, with no options in between.
What do I need to do to accomplish this?Started By Monte on Feb 26, 2009 at 7:09:08 AM | | | 17 Response(s) | Reply |

This message has been edited.cache?
Did you have something like
URL += "&ms=" + new Date().getTime()
at the end of your URL querystring when you are sending the ajax request?
Monte on May 24, 2009 at 5:07:03 AM (# 12)Nope. I'm getting everything from a web service I created.
BachusII on May 24, 2009 at 12:15:51 PM (# 13)<lurk stop="temporary">
"source" (as supplied by server) versus "generated source"? (as supplied by server PLUS any changes introduced client side, e.g. JS using a json object to populate a select element?)

I'll have to get back to you on that. I'll check on Tuesday (hopefully) when I get back to work and let you know.
MHenke on May 25, 2009 at 2:45:25 AM (# 15)Well, it's not that someone already mentioned the difference betweeen "view source" and "view generated source". :)
